Spool



momma M. W. BECKER SPOOL Filed Feb. 21, 1934 INVENTOR gig 214s W300?ATTORNEY Patented Oct. 8, 1935 UNITED STATES PATENT OFFIQE 2 Claims.

The present invention relates to spools and more particularly to thetype adaptable in intermediate thread winding operations.

An object of this invention is to provide a spool of the type describedof novel and improved construction, whereonto a thread is easilyattached with no loose or dangling end.

Another object of this invention is to provide a novel spool upon whichno waste threads occur which need to be stripped off.

A further object of the present invention is to provide a spool of thetype mentioned, onto which a thread is attached and the free end cut offin but one stroke of the hand.

Another object is to provide a spool of the character described whicheliminates the operation of making a few turns of the thread about itsshank to secure the end of the thread to be wound thereon.

A further object of this invention is to provide an article of the classmentioned, which is simple in construction, cheap to manufacture, easyto work with, which effects a saving in time, and which is efficient anddurable in use.

To attain these objects, in an embodiment of my present invention, Iprovide a spool with a strip metal thread grip, an edge of which servesas a cut-off to sever the loose end of the thread being attached to saidspool.

This invention is capable of numerous forms and various applicationswithout departing from the essential features herein disclosed. It istherefore intended and desired that the embodiment shown herein bedeemed illustrative and not restrictive, and that the patent shall coverwhatever features of patentable novelty exist in the inventiondisclosed; reference being had to the appended claims rather than to thespecific description herein to indicate the scope of the invention.

In the accompanying drawing, forming part of this application, similarcharacters of reference indicate corresponding parts in all the views.

Fig. 1 shows in perspective, an embodiment of my present invention.

Fig. 2 is an enlarged fragmentary sectional view taken at lines 22 inFig. 1, showing the construction of the thread grip and cut-off membermounted onto the shank of the spool.

Fig. 3 is a pictorial view showing a thread being slipped into thethread grip.

Fig. 4 is a similar view showing the loose end of the thread severedfrom the gripped thread.

Fig. 5 shows the metal strip used to form the thread grip and cut-01fmember.

Fig. 6 shows a side view thereof.

Fig. 7. is a section taken at line 'I-I, in Fig. 2.

In the drawing, the numeral I8 designates a spool provided with a recessI I in the shank thereof, of exact shape to receive a grip and cut-offmember I2, which is of strip steel or like material, bent flat in halfto pinch grip a thread I3, which may be inserted between the contactinghalves I4 and I5, of said member I2. The lower free end of the outer orexposed half Id of this member I2, has its inward edge beveled tofacilitate entrance of the thread I3. This member i2, is also shaped toconform to the curvilinear contour of the shank of the spool IQ, and issecured to same by a screw It passed through the registered holes I!near the top end of each half of the member I2; the head of same beingcountersunk to present an even surface.

It is to be noted that the member i2 is tiltingly mounted with respectto the axis of the spool III; the recess I I being deeper at its upperthan at its lower end to accomplish such construction. This is done sothat the lower end of half I5 is flush with the shank of spool It, toprovide a smooth and unbroken path for the thread I3, when it ismanually inserted between the halves of member I2. The side edges of thehalf It are slightly sharpened, to permit the thread to be cut thereon.The recess I I should be so fashioned that member I2 when mountedtherein, is flush with the shank of the spool It) as best as can beattained.

In use, when thread is to be wound onto the spool III, it is positionedso that a thread I3 held in hands I8 and I9 is slipped into the memberI2 by an upward motion, and simultaneously, hand I9 which holds the endof the thread, is brought abruptly upward, whereby the loose end 20 iscut off on the edge of the half I4. Thus the thread I3 is secured to thespool I0, without a dangling end.

As heretofore practiced, the free end of the thread was manually wound afew turns about the shank of the spool, leaving a dangling end whichcaused interference by becoming entwined in subsequent layers wound onthe spool. When the spool would be unwound in further windingoperations, this entwined end would cause frequent breaking of thethread and thus cause much waste, especially in the last layers to beunwound, which would necessarily require that they be stripped off witha knife. With my present device, such objections are entirely obviated,since they do not occur.

In use, when the wound spool is to be unwound, it is positioned so thatthe threads secured end will leave the member I2 by moving upward frombetween its halves I4 and I5. Therefore, in an unwinding operation, thespool 10 is set upside down with respect to its position when it isbeing wound, so that the secured end of the thread l3 will have easyexit from within the member I2.

In the Figs. 3 and 4, the spool I0 is shown in position preparatory tobe wound with thread from a skein; the spool receiving its motion from aslowly revolving table 2!, upon which it rests.

Having disclosed my present invention, the construction of an embodimentthereof and the manner of its use, I claim;-

1. In a device of the character described, a spool provided with asloping recess, and a memher having contacting strip elements mounted inthe recess and secured to the spool at the deeper end of the recess,adapted to receive and grip a thread between them; the surface of theinward strip element, at the shallow end of the recess being flush withthe surface of the spool to provide a smooth path for the introducedthread, an edge of the outer strip element being adapted to cut'thedangling end of the thread gripped between the elements, and saidelements being formed to conform to the contour of the surface of thespool, also the free ends of said elements being slightly spaced tofacilitate the insertion of the thread between them.

2. In a device of the character described, a spool provided with asloping recess and a member comprised of strip metal, mounted in the i0recess and secured to the spool at the deeper end of the recess, adaptedto grip a thread inserted beneath same; the free end of said stripmember being formed to conform to the surface of
